LOV2 blue light sensory domain
Protein DomainLOV2 is a blue-light sensory domain from Avena sativa that was fused into the anti-CRISPR protein AcrIIC3 to create light-switchable inhibitors of Neisseria meningitidis Cas9. In this engineered context, AcrIIC3-LOV2 hybrids inhibited Nme Cas9 in the dark and permitted genome editing under blue light in mammalian cells.
